Health Hazard Evaluations (HHEs)

Each month we will update this page to highlight newly released final reports and information on new and emerging hazards we are evaluating. Check back often to see what we are up to!

What's New

Evaluation of Exposures at an Electronics Recycling Company

HHE Program Investigators found metals in the air and elevated blood lead levels among employees. Employees were also exposed to flame retardants in the air, on their hands, and in their blood and urine. Investigators recommended adding local exhaust ventilation, stopping dry sweeping, and providing onsite laundering facilities or contracting with a laundering service.

Characterizing Exposures During Laser Tattoo Removal in a Hospital Dermatology Center

Although we measured low levels of some metals, VOCs, bacteria, and particles, none of our results were above occupational exposure limits. HHE Program investigators recommended strengthening the laser safety program by replacing laser protective equipment when worn out or damaged and only using “laser in use” signs when lasers are being used.
